Certified Ophthalmic Assistant Practice Exam

Sustained fixation without nystagmus is essential to ensure maintenance of fixation during an eye examination. Nystagmus refers to involuntary eye movements that can affect the accuracy of the examination results. By maintaining sustained fixation without nystagmus, the patient's eyes remain stable, allowing the ophthalmic assistant to accurately assess visual acuity, eye movements, and other important aspects of the eye examination. Choices A, B, and C (Intermittent blinking, occasional saccades, wandering fixation) do not contribute to the necessary stability and focus required during an eye examination.
